Find the common difference of the sequence shown 1/6,1/3,1/2,2/3,......
tekilochka [14]

Answer:

Common Difference(d) is    

               d=\frac{1}{6}

Step-by-step explanation:

Given sequence is :

                 \frac{1}{6}, \frac{1}{3} ,\frac{1}{2} ,\frac{2}{3} .........

If a sequence has a constant common difference throughout the sequence, then the sequence is called Arithmetic Progression.

Considering a sequence:

       a_1,a_2,a_3,a_4..........\\

a_2-a_1=a_3-a_2=a_4-a_3=a_n-a_n_-_1=d

where 'd' is the common difference of the A.P.

Similarly, finding the common difference of the given sequence.

       

                           \frac{1}{3} -\frac{1}{6}= \frac{1}{2}- \frac{1}{3}=\frac{2}{3} - \frac{1}{2}=d\\

                              d=\frac{1}{3}-\frac{1}{6}=\frac{(2)(1)-(1)(1)}{6}=\frac{1}{6}

                                   d=\frac{1}{6}

Common Difference(d) is    

               d=\frac{1}{6}

Not sure if im right. the random variable would be new jobs?
IRINA_888 [86]
Actually, the random variable in this case would represent the company. You can think of the random variable as an independent variable. If X=1 represents Lowe's, X=2 represents Intel, and so on, then the independent variable would be some given company and the dependent variable would be the number of new jobs pertaining to company x.

Which of the following are measurements of the sides of a right triangle?
viva [34]
For a triangle to be right angled  the largest side  squared must equal the sum of the squares on the other 2 sides ( Pythagoras theorem)

1.   101^2 = 99^2 + 20^2   so its is right angled

2. 28^2  is not equal to 26^2 + 12^2  - not right angled

3.  17^2 not euql to 14^2 + 6^2 - not
